MDI windows are
displayed.</p>
<p>QMdiArea functions, essentially, like a window manager for MDI
windows. For instance, it draws the windows it manages on itself
and arranges them in a cascading or tile pattern. QMdiArea is
commonly used as the center widget in a <a href="qmainwindow.html">QMainWindow</a> to create MDI applications, but
can also be placed in any layout. The following code adds an area
to a main window:</p>
<pre class="cpp">
     <span class="type"><a href="qmainwindow.html">QMainWindow</a></span> <span class="operator">*</span>mainWindow <span class="operator">=</span> <span class="keyword">new</span> <span class="type"><a href="qmainwindow.html">QMainWindow</a></span>;
     mainWindow<span class="operator">-</span><span class="operator">&gt;</span>setCentralWidget(mdiArea);
</pre>
<p>Unlike the window managers for top-level windows, all window
flags (<a href="qt.html#WindowType-enum">Qt.WindowFlags</a>) are
supported by QMdiArea as long as the flags are supported by the
current widget style. If a specific flag is not supported by the
style (e.g., the <a href="qt.html#WindowType-enum">WindowShadeButtonHint</a>), you can still
shade the window with showShaded().</p>
<p>Subwindows in QMdiArea are instances of <a href="qmdisubwindow.html">QMdiSubWindow</a>. They are added to an MDI
area with <a href="qmdiarea.html#addSubWindow">addSubWindow</a>().
It is common to pass a <a href="qwidget.html">QWidget</a>, which is
set as the internal widget, to this function, but it is also
possible to pass a <a href="qmdisubwindow.html">QMdiSubWindow</a>
directly.The class inherits <a href="qwidget.html">QWidget</a>, and
you can use the same API as with a normal top-level window when
programming. <a href="qmdisubwindow.html">QMdiSubWindow</a> also
has behavior that is specific to MDI windows. See the <a href="qmdisubwindow.html">QMdiSubWindow</a> class description for more
details.</p>
<p>A subwindow becomes active when it gets the keyboard focus, or
when <a href="qwidget.html#setFocus">setFocus</a>() is called. The
user activates a window by moving focus in the usual ways. The MDI
area emits the <a href="qmdiarea.html#subWindowActivated">subWindowActivated</a>() signal
when the active window changes, and the <a href="qmdiarea.html#activeSubWindow">activeSubWindow</a>() function
returns the active subwindow.</p>
<p>The convenience function <a href="qmdiarea.html#subWindowList">subWindowList</a>() returns a list of
all subwindows. This information could be used in a popup menu
containing a list of windows, for example.</p>
<p>The subwindows are sorted by the current <a href="qmdiarea.html#WindowOrder-enum">WindowOrder</a>. This is used for
the <a href="qmdiarea.html#subWindowList">subWindowList</a>() and
for <a href="qmdiarea.html#activateNextSubWindow">activateNextSubWindow</a>()
and acivatePreviousSubWindow(). Also, it is used when cascading or
tiling the windows with <a href="qmdiarea.html#cascadeSubWindows">cascadeSubWindows</a>() and
<a href="qmdiarea.html#tileSubWindows">tileSubWindows</a>().</p>
<p>QMdiArea provides two built-in layout strategies for subwindows:
<a href="qmdiarea.html#cascadeSubWindows">cascadeSubWindows</a>()
and <a href="qmdiarea.html#tileSubWindows">tileSubWindows</a>().
Both are slots and are easily connected to menu entries.</p>
